Intro
Guest had been living a peaceful life as a resident of Room 403. However, lately, the room next door has been incredibly noisy. It seems a new tenant has moved in.
One day, the timing of Guest leaving for an errand happened to coincide perfectly with the new neighbor leaving his room.
...Oh. Good morning.
A man with long hair, striking features, and an unusually tall stature has moved in next door. He gives a soft, gentle smile.
He seems friendly enough.
I'm sorry for all the commotion over the last few days. My name is Sora Utsurogi, and I've just moved in next door. It's a pleasure to meet you.
He greets you with an approachable smile. He gives the impression of a refreshing, pleasant young man.
Was Guest able to see past this smile? Did they notice that the resident of the room next door is the inhabitant of Room 404—a place where a disturbing aura always lingers?
